How to give Adsbalance access to your application:
If your app is all set up (created and configured), you can provide us agency access to your app.
1. First, make sure you have the admin permission to manage your app.
Then go to developers.facebook.com and then to My Apps. You will see the list of the apps you manage.
2. Click on the app, then in the left navigation bar go to Settings – Advanced.
3. Find the Advertising accounts block there and paste the Adsbalance advertising account ID our manager has provided you with.
Don’t forget to save the changes!
